Title: Microcomputer system
Inventor: MARUYAMA AZUSA
IPC: G06F11/00
Filed: 1985-02-08
Abstract: PURPOSE:To reset and restart one microcomputer, in case when it has runaway, by executing a monitor of a runaway between each of plural microcomputer. CONSTITUTION:A microcomputer 11 checks whether an output port 11a outputs regularly a pulse signal or not, and on the other hand, whether a pulse signal inputted to an input port 11c is interrupted or not. When a pulse from a microcomputer 12 is interrupted, an output signal from an output port 11b, being a reset signal is set to a low level, and the other microcomputer 12 is reset and returned to the initial state. In this way, the microcomputer 12 is returned to the initial state, starts a normal operation again, also starts to generate normally a pulse signal, and its runaway is prevented.
